how to add an HTA script into Explorer right click menu, just as vbs or bat file??

Hi,

OS: Win7 64bits Family

To add a vbscript or bat file to Win7 Explorer right click menu, ones does the following:

Within Explorer:
1. type "shell:sendto" into the address bar
2. drop the vbs, bat file

Now, in Explorer one selects any file and by right clicking on it, under "send to" one has our vbs or bat files. Great, but how to achieve this with hta files????

Thanks

P.S. I'm also happy on selecting a specify file type, for instance *.mp4 some kind of open with selection with my hta file.
